Abstract

A method and system for monitoring and controlling a power distribution system (10) is provided. The system includes a plurality of circuit breakers (16) and a plurality of node electronic units (20). Each node electronic unit is mounted remotely from an associated circuit breaker that is electrically coupled with one of the node electronic units. The system also includes a first digital network (22), and a first central control unit (24). The first central control unit and the plurality of node electronic units are communicatively coupled to the first digital network. The method includes receiving digital signals from each node electronic unit at the central control unit, determining an operational state of the power distribution system from the digital signal, and transmitting digital signals to the plurality of node electronic units such that the circuit breakers are operable from the first control unit.
